Zeiler SP-01 Speakers

The Zeiler SP-01 is a modern interpretation – and a homage – to the legendary studio monitors from Tannoy and Altec that were THE worldwide standard in recording and broadcasting studios in the 1960 and 70s.

While macro dynamic capabilities of these speakers are impressive it is the micro dynamic contrasts, which are so important for musical involvement, that benefit most. With these capabilities the SP-01 is the perfect speaker to match our pre- and power amps.

The SP-01 high-efficiency single-point source speakers provide seamless coherence and the dynamic capabilities that make them ideal companions for ZEILER pre- and power amps.

The “SP-01” loudspeakers are available in two high-quality surface finishes: piano high gloss or an elegant satin finish, characterized by its subtle, matte texture. Different colors for the enclosure and the front are available. The various finishes accommodate a range of design preferences, ensuring they blend seamlessly with your living environment.

Design

  • High-efficiency coaxial single-point-source speaker
  • Vented enclosure with variable bass port
  • Resonance optimized enclosure
  • The dimensions conform to the Golden Ratio principle, supporting resonance control
  • Enclosure walls are a compound of several wood- and non-wood layers of different density and hardness

Components

  • Professional 15 inch neodymium coaxial driver with carbon fiber reinforced paper cone
  • State of the art mid/high compression driver with 113 dB efficiency
  • Constant directivity wave guide projecting a constant 80×60 degrees up to the highest frequencies
  • Low-loss 2-way crossover featuring custom made paper-in-oil capacitors
  • Cryo treated internal wiring

Usability

  • High efficiency of 97 dB and 8 ohms minimum impedance provides an easy load for any amplifier
  • The speaker is designed to be used either with or without the front grille attached
  • Available in different color combinations for the enclosure and the front
  • Constant directivity of 80×60 degrees up to the highest frequencies avoids sweet spot for the listener
  • Variable port allows fine tuning the bass response to room size and wall distance
  • Adjustable feet allow for fine tuning the spatial projection of the speaker at your listening position
